PATIENTS HOPING TO GAIN BENEFITS| News of the creation of the world’s first cloned human embryos was welcomed by scientists, health experts and patients’ groups yesterday, while a few religious and pro-life groups voiced concerns. Ian Wilmut, who led the British-based Roslin Institute team that created Dolly the sheep, the world’s first cloned mammal, said the development carried major potential benefits for treating illness. “This is a very encouraging result because the ability to derive cells from cloned embryos would have several potential benefits that cannot be obtained in any other way,” Professor Wilmut said. He said the research could help to explain why genetic differences between patients lead to adverse responses to medicines, even if they are prescribed and taken appropriately. “Cells from such **milies could be studied in order to understand these mechanisms. In the longer term, when the cloning procedure has been improved, human cells may be used for treatment of degenerative diseases,” he said. |
